SEO - The grand schema things
Google, Yahoo and Bing have come together to provide a shared collection of schemas for webmasters to use. Schema.org provides a collection of schemas, i.e., html tags, that webmasters can use to markup their pages in ways recognised by major search providers. Search engines including Bing, Google and Yahoo! rely on this markup to improve the display of search results, making it easier for people to find the right web pages.
Many sites are generated from structured data, which is often stored in databases. When this data is formatted into HTML, it becomes very difficult to recover the original structured data. Many applications, especially search engines, can benefit greatly from direct access to this structured data. On-page markup enables search engines to understand the information on web pages and provide richer search results in order to make it easier for users to find relevant information on the web. Markup can also enable new tools and applications that make use of the structure.
Exciting stuff, if, like us, you're into this kind of thing. Schema.org could change the way people design websites and do search marketing so we'll be keeping a very close eye on how it all develops.
